The CISCO CWDM-SFP-1510 module is a high-performing, pluggable transceiver designed for use in Gigabit Ethernet and Fibre Channel networks over single-mode fiber. Operating on a 1510 nm Coarse Wavelength Division Multiplexing (CWDM) wavelength, this module is part of a series of transceivers that enable the implementation of a cost-effective, scalable, and flexible wavelength-division multiplexing (WDM) strategy in the network infrastructure. It is capable of transmitting data at rates of 1 Gbps for Ethernet and up to 2 Gbps for Fibre Channel applications, over distances up to 80 kilometers, depending on the fiber quality and other factors. The integration of CWDM technology allows for the transmission of multiple, distinct wavelengths over a single fiber strand, significantly increasing the capacity of existing fiber infrastructure without the need for laying additional cables. The CWDM-SFP-1510 module's compliance with multi-source agreement (MSA) standards ensures interoperability with a wide range of networking equipment. It also features Digital Optical Monitoring (DOM) support for real-time access to device operating parameters, offering network administrators enhanced visibility into the network's performance and the ability to preemptively identify and address issues. Tailored for long-distance, high-capacity networking applications such as service provider backbones, enterprise networks, and data center interconnects, the CISCO CWDM-SFP-1510 transceiver is a strategic component for organizations looking to optimize their optical network efficiency and scalability.
